We consider propagation and interaction the extremely short pulses in ferroelectric media possessing both the nonlinearities of the third and fifth orders. Using to the analytic expressions found previously, the stability of the stationary pulses to additive modulation and interpulse collisions is demonstrated by numerical simulation. The stability of electromagnetic domain is proved regarding the interaction to the incident solitary wave.

Keywords: extremely short electromagnetic pulses, ferroelectrics, paraelectrics, domain
walls, stability.
